Hi Tony,
Still a bit of family mystery i am afraid and still trying to find out. I have traced the baldwins as far back as i can. My grandad was William (Bill) Martin who was the brother of our Aunty Doris. Happy to compare notes and strangely i live in Haywards Heath so we are not far. I dont know your connection but be great to say hello. My my mum is Joyce martin.
My number is 07899 996166 if you fancy saying hello
best wishes
Andrew
